to Drive Improvement
Value
of Products & Services
Environmental
Impacts
Possible Measures of Value
•Sales or Net Value
Added
•Product Volumes
Possible Measures of Impacts
•Proxies like total consumption of raw materials, or net energy used
•Particular consumption levels, eg water or reagents
•Net emissions, eg Greenhouse gases, SO2, heavy metals, toxics
etc
•Waste stream volumes
The underlying intent
is to significantly decrease environmental impacts and maximise the value
delivered
•A good starting point is a mass and energy balance, ie. a clear
understanding of inputs and outputs of major and minor species
•Analyse behaviour and outcomes to be encouraged and then set
metrics, not vice versa
•Tailor the analysis to specific business dynamics and local ecological
issues
•Targets can be developed based on volume or percentage
improvements, as well as the extent of opportunities realised or the fraction of hazardous
materials recovered
